Bigfin Reef Squid

We couldn't resist showing another image of this otherworldly animal! The species is one of many that visitors can see in our new Tentacles special exhibition. We hatch bigfin reef squid from eggs sent from Indonesia and Japan using a technique pioneered by our aquarists. Hundreds of "pods," each containing two to six embryos, are suspended so we can monitor their growth. The squid are barely a quarter-inch long when they hatch, but can grow to more than a foot. 

Bigfin reef squid have eight arms and two tentacles; the latter are used for capturing prey and guiding it to their sharp beaks. Their "big fins" extend the length of their bodies, hence the name. Extremely fast growing, these squid can eat up to 30 percent of their body weight per day.
